LarsS Posted March 20, 2009 Share Posted March 20, 2009 I am experiencing some trouble getting a system stable. I installed Ubuntu 8.10 but have experienced stability problems not normal to Linux (freezes etc.). Runnig memtest3.5 at one stick at a time in the first slot (i.e. testing them one at a time) revealed problems with 3 out of 4 sticks(!) Went back to dealer who gave me new sticks, and these were all OK in testing one by one. I then populated all memory slots and ran memtest again (memtest 2.01 this time, supplied on Ubuntu install CD). This test gave errors in test #5 (block moves), but only for the second bank / channel. The mobo is not listed in Corsairs memory configurator, nor is the memory listed in ASUS' QVL for the mobo, but these are the sticks the dealer said I should use, and that that they *should* work, but may require BIOS adjustments. But what would be the good adjustments to try? So far I only tried increasing the mem voltage from the default 1.85 V to 1.91 V (as these sticks are apparently supposed to operate at 1.9 V acc. to the corsair website), but the problems prevail. So any help on the strategy to use to try and get this stable would be much appreciated (lower mem clock? other?). Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 20, 2009 Corsair Employees Share Posted March 20, 2009 With 4 modules I would suggest setting the memory frequency at DDR667 and set the memory Voltage to 2.0 Volts and set the NB/MCH/SPP Voltage to +.2 Volts as well and test the system with http://www.memtest.org. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test. Link to comment Share on other sites More sharing options...
LarsS Posted March 24, 2009 Author Share Posted March 24, 2009 Thanks for the tips, setting frequency down to 667 has stabilised the system and it's running smoothly now. I had 3 consecutive runs of memtest OK so, all seems well. Cheers, Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 24, 2009 Corsair Employees Share Posted March 24, 2009 NP test it with windows to make sure its 100% stable. Link to comment Share on other sites More sharing options...
